Product details
1. Product Basic Overview
The Kawasaki K3VL45 is a premium variable-displacement Hydraulic piston pump serving as the core main hydraulic pump for Volvo winch trucks. It acts as the central power source of the vehicle’s whole hydraulic system, providing stable high-pressure hydraulic oil for winch lifting, traction, auxiliary driving and other heavy-load operations of the winch truck, perfectly matching the original design parameters of Volvo’s mobile heavy-duty hydraulic layout.
2. Core Structure & Working Principle
Structural Composition
This swash-plate open-circuit Hydraulic piston pump adopts Kawasaki mature optimized gerotor and cylinder block assembly, integrated multi-mode control valve set, heavy-duty roller bearings and high-pressure sealing modules. It features compact overall layout, strong radial load capacity, and can be directly mounted on the power take-off end of Volvo winch trucks to connect with the host hydraulic system seamlessly.
Operating Logic
Mechanical power from the truck engine drives the pump shaft to rotate, pushing pistons to reciprocate in the cylinder block. The swash plate angle changes to adjust displacement, converting mechanical energy into high-pressure hydraulic energy. The pressurized oil is delivered to each executive component of the hydraulic system, realizing stepless adjustment of winch winding speed and output torque; built-in load-sensing and constant-pressure modules automatically match flow output according to load changes, cutting energy waste of the whole hydraulic system.
3. Outstanding Performance Advantages
- Top-tier efficiency & stable output: Peak efficiency exceeds 90%, unique pressure pulsation suppression structure reduces vibration and noise greatly, making this hydraulic pump run smoothly during frequent start-stop and reversing of the winch truck.
- Rich control compatibility: Supports load sensing, constant pressure, horsepower limitation and remote unloading control, flexible to adapt complex loop logic of Volvo winch truck’s hydraulic system, avoiding system overpressure damage under heavy hoisting conditions.
- Strong harsh-environment adaptability: Continuous working pressure up to 320bar, excellent self-priming performance, premium wear-resistant sealing adapts to dust, vibration and wide temperature changes on construction sites, extending the service cycle of the entire hydraulic system.
- Plug-and-play replacement: Standard SAE mounting flange and spline shaft are fully consistent with Volvo winch truck original installation dimensions, no pipeline modification required for aftermarket replacement, lowering maintenance downtime of the hydraulic system.
4. Key Technical Parameters
- Model: K3VL45 (Kawasaki genuine Hydraulic piston pump)
- Nominal displacement: 45 mL/rev
- Continuous working pressure: 320 bar
- Max allowable rotating speed: 2700 rpm
- Matching object: Volvo heavy-duty winch truck original hydraulic system

5. Application Scenarios on Volvo Winch Truck
As the core main hydraulic pump, it supplies power for all key actuators in the truck’s hydraulic system:
1. Main hydraulic winch: Heavy load winding, releasing and braking for rescue, logging and engineering traction;
2. Auxiliary hydraulic devices: Outrigger stretching, lifting bracket adjustment and on-board material handling mechanisms;
3. Emergency working conditions: Stable power output for slope parking and heavy-load traction to guarantee system safety.
